Semintra is what my friend’s cat has been put on, despite not doing a urine test. It is actually a blood pressure medication, but they use it to help kidney function, my neighbours cat was on it for high blood pressure, although she had slight kidney issues too. The out of hours thing is a big thing, my neighbour wont change as even though the distance between mine and hers is similar if you need it at silly o’clock, she doesn’t like the drive to mine, but I prefer it as it is the main branch of my vets, so access to all their records, when you have cats with unusual, multiple health issues, that is a big bonus! And now they have stopped the out of hours consultation charge, so no worry about how much extra it will cost. Most people don’t even need to use it, but I think it needs to be factored in when choosing a vet.
